//         this script enables you to use so many slideShows as you want to                //
//         have on your page without any extra-programming.                                    //
//         Only you must do is to set the paths and image-names!                               //

//              - each slideShow has its own slideShowSpeed and crossFadeDuration      //
//              - choose between random or in the order                                   //
